Just got the Primus a week ago and I am delighted with it. It has a user friendly interface so it is very easy to use. If you are looking for a lot of power at an affordable price. ... well look no further !!! It delivers a lot and I mean A LOT of power while being easy to use and it is not expensive. It is a bit heavy but keep in mind it runs on 3 batteries so if that doesn't bother you than you have to get this. It is a nice looking mod ,no shaking noises from the buttons . The battery door gives me the impression that it will just come off but it has not happened yet , truth being said I am more used to stronger magnetic covers. All in all it is a great device that I highly recommend but not for the faint hearted . (Posted on 13/07/2016)
